Webmiss: 
Tonks Metamorphagus
Tonks was born a Metamorphmagus, which means that she can change her appearance at will. She uses this ability in service to the Order, but it also helped her qualify as an Auror (she got by without even studying)!
in the books she morphed into the following:
While explaining to Harry about a metamorphmagus: Bubble Gum Pink hair
While entertaining Hermione and Ginny at meal time: Nose changes from beak-like protuberance of Snape’s, shrinks to button mushroom, sprouts lots of hair from each nostril and finally ends with a pig snout - a favorite of the girls’.
Waking up and saying good morning to Harry: Blonde and curly hair
Explaining that she was never a Prefect: Tomato-red and waste length hair
Greets on the corner: An old woman with tightly curled gray hair and wore a purple hat shaped like a porkpie
Escorting Harry outside: tall, tweedy woman with iron-gray hair
